Abstract
We must avoid pulmonary vascular injury most of all in the lung surgery. Surgeons have faced the surgery after reading the anatomy of the pulmonary vessels from CT findings prior to surgery in the past. However, we can encounter an unexpected branch of vessels by chance during an operation because many variations of the pulmonary vessels exist. Therefore, it is crucial to have correct understanding of angioplany preoperatively. We report a case of lung cancer in which surgery was safely performed by keeping pulse on the exceptional branch of V2 terminalis by three-dimensional angiography including the bibliographic consideration. The exceptional branch of V2 terminalis predominantly appears in men and in the right side. It often drains into the left atrium and can be associated with the angioplany of the bronchus or the right aortic arch.
